How do you replace the fuel pump on a 1990 Nissan 300zx?
I am almost positive these are just like the firebirds and camaros. If you lift the carpeting in the trunk, there should be a circle shape in the metal, close to the back of the back seat. I believe it unscrews, or unbolts and the fuel pump is right there. This was done in order to prevent having to drop the whole tank. Secondly, be careful when taking out, as the floater device is still attached.
